The note, dated Monday, states that management does not currently set a date for reopening the 1508 Riverdale St. establishment. “We apologize for any inconvenience,” the note stated.

“I’d like to thank each of you for your loyalty throughout the years and hope that we may have the chance to serve you again in the future. Questions and concerns can be placed by calling the corporate office at (617) 720-2100.” The note is signed “Piccadilly Pub Restaurant.”

No one was available for comment from the corporate office late Tuesday afternoon.

The West Springfield restaurant was opened in 1995 on the site of the former Vincent’s Steak House. It was the 10th Piccadilly Pub Restaurant opened by Piccadilly Management Group Ltd. and the first in Western Massachusetts.

The Telegram & Gazette in Worcester reported Monday that the restaurant chain apparently closed a number of its restaurants that day.

Worcester, Auburn, Sturbridge and Westborough locations were shuttered, with notices of closing posted on the doors by the Massachusetts Pub Group, which operates the chain, according to the Worcester newspaper.

The Piccadilly Pub is a chain of nine casual dining restaurants that started in Westborough in 1973, the newspaper stated. In Central Massachusetts, the chain has locations in Sturbridge, Auburn, Worcester, Westborough and Marlborough, according to the Telegram & Gazette.
